Copper IUD

A Copper coil IUD (also called a Copper IUD or IUD) is a small plastic T-shaped device that is implanted into the womb (the uterus) to prevent unwanted pregnancies. It is temporary but long-lasting, and does not need extra attention for 5-10 years (depending on the type) after it is put in.[1] It is over 99% effective,[1] and one of the most effective forms of birth control women have. It can be used as a form of emergency contraception.[1]
The T-shaped IUD has two soft threads hanging from it, which hang from the womb to the top of the vagina. These are felt by the woman to make sure it is still in place.[1]
Copper IUDs do not use hormones to prevent pregnancy. They work by releasing copper into the woman.[1] They do not work by the copper killing the sperm. They are a slightly different form of birth control to the intrauterine system (IUS), which uses hormones instead of copper.
They are not suitable for everyone, and they are put in at a doctors clinic or GP.[1] They do not work in people that are already pregnant, have an STI or pelvic infection, or have problems with their womb or cervix, or bleeding from the area.[1] Having an IUD fitted takes 5-10 minutes and starts working immediately. They can be implanted quickly (within 48 hours) after giving birth, but usually they are fitted from 4 weeks after birth.[1]
The IUD might cause extra bleeding after it is fitted, or heavier periods which then usually resolve after a few months.[1] An IUD is very safe but extra risks include pelvis infection (usually 3 weeks after), the IUD coming out (3 months after), damage to the womb, or ectopic pregnancy.[1]
